Despite winning her first pageant at 10 months old, Ms Walker said her latest title came “completely out of nowhere”.

“I went into it not expecting much, maybe to learn or come back in the future,” she said.

“So I spent my time just enjoying myself, eating whatever I wanted to.

“I wasn’t really concerned. I’m a curvy girl, that’s just how I am. A lot of the girls were freaking out, saying ‘Oh, can’t eat that, gotta eat that’. I was like ‘This is how my body looks, a couple of pastries aren’t going to hurt me now’.”

Ms Walker said all seven Australian contestants made it into the top 25.

“I could hear a bunch of girls backstage saying ‘Those damn Aussies, they’re going to take it out again this year’,” she said.

“There is something in the water, absolutely.”

Between working at the University of WA and planning a road trip around Australia with her boyfriend, Ms Walker said she was hoping to expand her modelling and pageantry work into TV presenting.

“I’m just going to concentrate on myself, owning this title and being the best person I can be,” she said.
